Filing calls for injunction on TiVo imports

Microsoft has filed a complaint with the International Trade Commission, accusing TiVo of patent infringement and calling for a ban on TiVo imports to the US. The filing is focused on Microsoft's patents related to technology used in the company's Mediaroom software, which is utilized in various set-top boxes, such as AT&T's U-verse hardware, that provide DVR functionality.

The ITC request is the latest move in an ongoing legal battle that began a year ago when Microsoft filed a formal lawsuit against TiVo. The latter company also faces a similar patent-infringement lawsuit originally filed by AT&T. Microsoft filed its own action after attempting to join in AT&T's suit.

"Microsoft seeks an order excluding TiVo's infringing set-top boxes and associated software and hardware from entry into the United States and a cease and desist order or orders halting the domestic sale of infringing, imported set-top boxes and associated software and hardware," the filing reads.
